摘要：In this study, growth parameters of the non-native Silver Crucian Carp (Carassius gibelio Bloch 1782) in the Seyhan Dam Lake were investigated between June 2013 and May 2014. The length ranged from 14.5 - 32.7 cm, weight varied between of 52 - 607.46 g while age composition changed from 0+ - V. the group. The length-weight relationship was W=0.0107xL~(3.0095 )(R~2=0.9391) for females. It was determined that feature positive allometric growth for growth females. von Bertalanffy growth constants in length and weight were as L_∞ = 36.60 cm, W_∞ = 835.475 g, K = 0.320 year~(-1 )and t_0 = - 0.2986 year. Natural mortality rate M = 0.74 year~(-1 ), total mortality rate Z = 0.77 year~(-1 ), fishing mortality rate F = 0.03 year~(-1 ) and exploitation rate E = 0.04 year~(-1 ) was estimated. Silvery Crucian Carp in Seyhan Dam Lake have proliferated excessively and has already invaded our respective reservoir completely.
